Code Compliance Research Report (CCRR) confirms system’s IBC and IRC compliance

Knowing that every aspect of the steel deck framing has been tested brings peace of mind and provides customers with an easy to assemble, fully compliant system.

Fortress® Evolution steel deck framing is now fully verified for “Structural Performance” by Intertek, an independent assurance, inspection, product testing and certification company. A Code Compliance Research Report (CCRR) issued by the third party organization confirmed that Evolution steel deck framing adheres to the structural performance standards in the 2018 International Building Code® (IBC) and 2018 International Residential Code® (IRC). With this designation, Fortress can offer commercial and residential building professionals a proven, enduring framing solution tested for safety.

To verify compliance, Intertek rigorously tested the entire cold-formed steel deck framing system. This included Fortress Evolution steel deck framing, joists, ledgers, rim joists, beams, support posts, brackets and connectors, and more. Fortress offers all of these components in one comprehensive package as a Total Solution.

“This full certification applies to even the connection details for all of Fortress’ steel deck framing system parts,” says Rob Holthaus, Product Manager for Fortress Building Products. “This is a key differentiator, as other framing products on the market don’t provide the connectors themselves. Knowing that every aspect of the steel deck framing has been tested brings peace of mind and provides customers with an easy to assemble, fully compliant system.”

In addition to detailing Fortress Evolution steel deck framing code compliance, the CCRR draws from Intertek’s engineering analysis to provide at-a-glance performance benchmarks, such as the deck substructure’s maximum spans. This information allows builders to use the CCRR as a roadmap to constructing a deck framing system and more fully realize the possibilities available with light-gauge steel.

“We’ve worked hard on achieving this designation, so it’s a great feeling to have Fortress Evolution steel deck framing demonstrate code compliance. Now, commercial and residential builders alike can have total confidence in choosing a steel deck frame and better understand the system’s capabilities,” Holthaus concludes.

Fortress Evolution steel deck framing is an integrated, easy-to-assemble system. The smart, interlocking joist and ledger system uses light-gauge steel with commercial-grade strength. Steel joists come in a familiar shape, installing quickly and simply with minimal fasteners. The design also includes a Ledger Bracket that eliminates the need for excessive fasteners and speeds up installation. Engineered to last 25 years or more, Evolution steel deck framing provides dimensional stability to ensure surface boards remain flat and smooth. The system provides greater spans between supports, increased safety ratings and is invulnerable to rotting, warping, splitting and insect damage. In an industry first, steel stair system components and brackets work with Evolution joist and beams to create a complete steel deck framing system. Intertek is currently testing the Evolution steel deck stair system.
